Jump Liners
MIG Welding Accessory
Issued Jan. 2013 • Index No. SPEC JL-1.5
All Consumables are Not
Created Equal.
It's important to choose longer
lasting consumables. They can make
the difference between repeated
consumable replacement and rework, or
more arc time and better bottom line.
Jump Liner
Jump Liners replace only the most commonly
worn and clogged liner area to reduce the
amount of time a gun is offline and minimize
inventory.
Enable quick and easy neck change-out so gun
can be easily adapted to fit multiple applications.
Fit all Q-Gun™ and S-Gun™ MIG Guns - from
150 to 600 amp.
Available in sizes to fit .023" (0.6 mm) to 1/16"
(1.6 mm) wire.
